Depends on the platform. The ASR1000 does IPSec and other 
security stuff in hardware with no CPU impact. I suppose 
that's what the OP meant.

I'd choose an ASR1000 for security over an ASA because it 
has better routing than the ASA, except, of course, there 
are specific security features that only the ASA can 
support.

But otherwise, if the playing fields are level, I'd go with 
the router:
